Tunneling Techniques
When IPv6 development and antecedent deployment began in the 1990s, best of the world’s networks
were already congenital on an IPv4 infrastructure. As a result, several groups accustomed that there was
going to be a charge for means to carriage IPv6 over IPv4 networks, and, as some bodies anticipated,
vice versa.
One of the key affidavit for tunneling is that today’s Internet is IPv4-based, yet at atomic two major
academic and analysis networks use IPv6 natively, and it is adorable to accommodate mechanisms for
hosts on those networks to ability anniversary added over the IPv4 Internet. Tunneling is one of the ways
to abutment that communication.
As you may gather, tunneling meets a cardinal of needs in a alloyed IPv4 and IPv6 world; as a result,
several kinds of tunneling methods accept emerged. This area looks at several of them and
examines one in detail.
